Compost designs

ROTATING BARREL COMPOSTER - I want to make one of these. It says that the materials should only cost about $60 which is alot better then the ones you can buy at the store...

This model is about $180.00, which I can't see spending on a composter.

My dad loves making stuff, maybe I could buy the stuff and he and I could put it together! That sounds fun!!

I want to get a rotating one so that I don't have to stir and move the stuff around myself, yuck...Also, last night my Aunt Janna told me that one of our church friends does composting. So, I definitely have to pick her brain!
